To all 'whom 'it mcy concern:

Be it known that I,'JOHN RANK, of Minne. apolis, Hennepin county, Minnesota, have invented certain new and useful Improve-y ments in Grease-Cupa'of lwhich the following is a specification.

My inventionrelates to grease cups de? signed particularly for use onv'moving. bearings such as crank pins andeccentrics, and

the object, of the invention is to provide a cup having means for a osi'tive and reliable feed of the grease, and a so having `means by means of which the feed maybe regulated.

.'-The invention consists generally in various constructions and combinations, all asheref inafter described and particularly pointed out 'in the claims.

'In the accompanying drawings, lforming part of this specification, Figure 1 isja detail view partially in section illustrating the application of my grease cup toacrank -pin bearing. Fig. Z is a side view of the cup removed froni the bearing. Figl 3 is a detail view illustrating the manner of fitting a nipple into the bottom of the cup.

.In-the drawing 2 represents a shaft, 3 a crank secured thereon, 4 acrank pin and 5 a pitman or connecting'ro'd. A passage 6 isl .provided in the'bearing ofthe rod leading to the pin 4. l l

7 isa cup, conical in' form having a bushing 8 fitted into its lowerend, and a mpple 9 with one end inserted into said bushing and the other end tapped into the bearing of the I V crankpin above the passage 46.

lower end Within the :passage 6 and contacting with the crank pin, audits upper end' passing througha cover 11' that is mounted on the cup and provided with bayonet slots 12 to receivepins 13. An adjustable collar 14 is mounted on the rod 10 below the cover and a similar collar 15' is mounted on the rod 'a cone 16 also adjustable on the rod 10 and adapted to fit into the upper end of the bush-l ing 8 and .close the passage therethrough.

-By moving this cone up and down on the rod..

, base of t 10 1s a rod preferably of copper having its..

I am able to regulate the vot of grease fed to the bearing. l

Inadjusting the devi-ce preparatory teus@ I secure the cone 16 eri-the reused attore' it., to drop down into the bushing. Ehen this t@ collars 14 and 15 are put in ace and by lifting the collar 15 the rod an the cone 16' will be raisedl also and the distance between the collar 15 and the cover will indicate the space between the cone and its seat in the c5 bushing. I am -thus able to accurately just the feed of thecup. The throw ofthe rod 10 or its strok lengthwise is determined by the ad'ustment of the collar 14when the cup is ed with 70 grease. The rod will act as a. contacting means land insure the deli-very of the grease to the-bearing. I make no claim particularly herein to the rod for. this purpose, as it is old 4in devices of this kind, my invention' 75 residing in the attachment of the rod.

. I t is frequently necessary to provide different sizes of fittings for mounting a grease A cup of this kind. I have therefore, as indi.-

cated in Fig. 1, provided means whereb ma bushing may be utilized, or as shown in ig'.

3, the ni 'ple may be tapped directly into the lie cup. I am thus able to adapt the fittings for thediie'rent sizes of holes 1n the bearing on which the cup is to be used.

The rod maybe adjusted incontact with the bearing or out of contact therewith as desired, and the degree of movement of the rodmay beregulated by the adjustable collars. In some instances I vmay prefer -to make the rod rigid, as in a fast moving bearing, so that there will be no longitudinal movement of the rod in the revolution of the crank pin and the cup.

'I 'claimas my invention: f

1. The combination, with a movable bearing, of a grease cup mounted thereon and having a suitable cover, a rod arranged within 'said cup and extending down intosaid bearing and up through said cover, and meanson said rod-l above and belowA said cover whereby vsaid rod is held rigid-or permitted a limited longitudinal movement in the revolution of the'bearing.

2. *Thecombinatiom with a movable bearing, of la grease 'cup mounted thereon and having a suitable cover, arod mounted in said cup and bearing, and collars ad'ustably mounted on'said rod above and belowl said coverand whereby said rodl is held or'llO permitted `to moveflongitudiually, foi" the purpose specified,

3. The combination, with a bearing, of a grease vcup mounted thereon. arid' having a passage leading to said bearing, a rod ai'-v rahged Within said oup and bearing and having a longitudinal movement, a cone adjustably mounted. on said rod and adapted to regulate the feed of the grease through sai'd passage, a @over for said @up through which said' rod extends, ,and-a oollai` adjustahlv mounted on said rod above said cover, and by means of whloh the adjustment of said cone and thefeed of the grease may be determned.

4. A greaselcup, having a cover and a so1,ose

an interiorly threaded bushing fitting within, .said opening and having 'iatleuod suilzuos for application of a 'Wrenchthereto, smid bushing heilig uitoi'lorly threaded, a nipple 'ittiug Within said bushing and having :L

fple, substantially as described.

lu Witness whereof l have hereunto set 1 l 7 i my hand this ist dafv ol' March 1903.
